Databases Unplugged: Challenges in Ubiquitous Data Management
The recent Asilomar Report on Database Research cites ubiquitous “information appliances” as a major driver for database systems research over the next ten years. For the present, however, the use of most mobile devices is mostly restricted to Personal Information Management (PIM) applications. In order to fully realize the potential of ubiquitous data access, such devices must be allowed to serve as an extension to the enterprise data management infrastructure. Thus, database technology must be adapted to deal with the limitations as well as the tremendous opportunities of large-scale mobile data access. Challenges exist in core database areas such as system architecture, query processing, and transaction management, as well as in emerging areas such as data dissemination and user-directed execution. In this talk I will outline several of these challenges and describe approaches that have been proposed to meet them.
